My parents will getting the kids first and DHs sister and husband are our back up.

We decided by who could support them financially, with the morals and values we have, and know that would be brought up as closely as we would have raised them.

I want my kids to stay together.
My parents and DHs sister would be able to provided for them and raise them as healthy, well rounded humans.
We also wanted them to stay with family. Be it grandparents or aunt/ uncle and cousins.

DHs mother will not be getting them. We do not trust how they will be raised with her.
